Toiall whom it may concern. I

Be it known that 1, DAVID BRANDFON, a citizen of the United States,residing at Los Angeles, in theicounty of Los Angeles and State ofCalifornia,'have invented new and useful Improvements in AdjustableChair-Recliners, of which the following is a specification. i i

My object is to make an adjustable chair recliner, and my inventionconsists of the novel features herein shown, described and claimed.

Figure 1 is a side elevation of a chair showing an adjustable chairrecliner em bodying the principles of my invention in use and supportingthe chair in a reclining position.

Fig. 2 is a rear elevation looking in the direction indicated by arrow 2in Fig. 1.

Fig. 3 is a side elevation of the clamp upon an enlarged scale, thesupporting frame being broken away.

Fig. 4 is a sectional detail of the movable clamping member upon anenlarged scale.

Fig. 5 is a, fragmentary rear elevation of one side of the supportingframe.

The chair 1 has a flat seat board 2, and the adjustable chair recliner 3is connected to the rear edge of the seat board 2.

The adjustable chair recliner 3 consists of side bars 4 and 5, crossbars6 and 7 rigidly connecting the side bars, and clamps 8 and 9 hinged tothe upper ends of the side bars4 and 5 and clamping the seat board 2.The clamps 8 and 9 are substantially alike and each clamp consists of aC-shaped frame 10 having a bearing 11 in its upper end and a bearing 12in its lower end, a compression screw 13 screw seated through thebearing 11 and having a clamping plate 14 swiveled upon its lower end, astem 15 sliding through the bearing 12 and having a spline 16 to holdthe stem from rotating in the bearing, a cam 17 mounted upon the bearing12 and having a handle 18, a cam 19 fixed upon the upper end of the stem15 with the stem extending through the cam 17, and the clamping plate 20formed integral with the cam 19, the clamping plates 14 and 20 being invertical alinement; so that when the screw 13 is adjusted, the rear edgeof the seat board 2 placed between the clamping plates 14 and 20 and thehandle 18 operated one way, the clamps grip the seat board, and when thehandle is operated the other way the seat board is released.

I Specification of Letters Pete.

The cams 17 and 19 are circular in plan, the. cam 17 having an upperface 21, and the 'camf19 having a lower face 22, so that when the cam 17is rotated'the face 21 slides under the face 22 to raise the'clampingplate Patented July 8, 1919. Application filed l liecemb er 5,1918."{serial No. 265,455.-

20.2mm the" cam 19 hasfa lo-wer'face23 on a higher level thanthe face i22, and the levgl than the face 21,"so that when the handle 18 is movedto a releasing position the face 23 engages the face 21, and the face 22engages the face 24. The faces 21 and 24 are connected both ways bycurved inclines, and the faces 22 and 23 are connected both ways bysimilar curved inclines, the inclines of one face fitting the inclinesof the other face when the clamp is released.

The upper ends of the side bars 4 and 5 are bifurcated to form thebearings 25 and 26 and the stops 27 and 28. The central portion of theframe 10 is T-shaped in cross section, and the flange 29 of the centralportion fits between the stops 27 and 28 and between the bearings 25 and26, and the bolt 30 is inserted through the bearings and through theflange to make a hinge connection, and when the lower end of the sidebar is thrown backwardly the stops 27 and 28 engage the flanges 31 and32 of the frame 10. The upper ends of the side bars 4 and 5 are metal,there being a ferrule 33 extending downwardly from the bearings 25 and26 and connecting the bearings together. The wooden stick 34 has areduced upper end fixed in the ferrule 33, and the crossbars 6 and 7connect the two wooden sticks 34 together. A sleeve 35 isslidinglymounted upon the lower end of the stick 34, there being a plurality ofbo lt holes 36 through the stick, and a corresponding pair of bolt holesthrough the sleeve to receive the bolt 37, so that by moving the bolt 37from one hole 26 to another the effective length of the side bar isadjusted. A wooden peg 38 is fixed in the lower end of the sleeve 35 toengage the floor.

In the practical operation, the adjustable chair recliner 3 is appliedto the seat boardthe person occupying the chair desires to recline, thelower end of the supporting frame is swung backward'ly and-the chairtilted backwardly until the frame enga 'es the floor, as shown in Fig.3; then" t e chair will stand solidly upon its two rear legs and uponthe recliner.

Various changes may be made without departing from the spirit of myinvention as claimed.

I claim:

An adjustable chair recliner comprising side bars, Crossbars rigidlyconnecting the side bars, C clamps hinged to the upper ends of the sidebars, compression screws screw seated throughthe upper ends ofthe Copiesofthis patent maybe obtained for cams mounted upon the lower ends of theC.

clamps around the stems, handles for operating the clamps, andsecondse'amsifixed upon the upper ends of the stems in engagement withthe" first cams and in opposition to the clamping plates so that by manp lat s th handl he'damPS m y p a seat board. I

In testimony whereof I have signed my m to this s eci tion:

DAVID BRANDFON.
